Description
The MPI series magnetostrictive level sensor provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. It is certified for installation in Class I, Division 1, and Class I, Zone 0 hazardous areas in the US and Canada by CSA, and ATEX and IECEX for Europe and the rest of the world.
How To Read Your Label
Each label comes with a full model number, a part number, and a serial number.
The model number for the MPI will look something like this:
SAMPLE: MPI-R5-ZY-P3SB-120-4D-N
The model number correlates with all the configurable options and tells you
exactly what you have.
Compare the model number to the options on the datasheet to identify your
exact configuration.
You can also call us with the model, part, or serial number and we can help
you.
You’ll also find all hazardous certification information on the label.

Installation Guidelines & Instructions
The MPI should be installed in an area–indoors or outdoors–which meets the following conditions:
- Ambient temperature between -40°F and 185°F (-40°C to 85°C)
- Relative humidity up to 100%
- Altitude up to 2000 meters (6560 feet)
- IEC-664-1 Conductive Pollution Degree 1 or 2
- IEC 61010-1 Measurement Category II
- No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.) (Not applicable to plastic-type stem options)
- Ample space for maintenance and inspection
Additional care must be taken to ensure:
- The probe is located away from strong magnetic fields, such as those produced by motors, transformers, solenoid valves, etc.
• The medium is free from metallic substances and other foreign matter.
• The probe is not exposed to excessive vibration.
• The float(s) fit through the mounting hole. If the float(s) does/do not fit, it/they must be mounted on the stem from inside the vessel being monitored.
• The float(s) is/are oriented properly on the stem (See Figure 5.1 below). MPI-E floats will be installed by the factory. MPI-R floats are typically installed by customers.
**IMPORTANT:** Floats must be oriented properly on the stem, or sensor readings will be inaccurate and unreliable. Untapered floats will have a sticker or etching indicating the top of the float. Remove sticker prior to use.
ATEX Stated Conditions of Use:
- Under certain extreme circumstances, the non-metalic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only be cleaned with a damp cloth.
- The enclosure is manufactured from Aluminum. In rare cases, ignition sources due to impact and friction sparks could occur. This shall be considered during installation.
Installation Instructions:
- When lifting and installing the sensor be sure to minimize the bending angle between the rigid stem at the top and bottom of the sensor and the flexible stem in-between. Sharp bends at those points could damage the sensor. (Not applicable for non-flexible probe stems.)
- If your sensor’s stem and floats fit through the mounting hole, carefully lower the assembly into the vessel, then secure the sensor’s mounting option to the vessel.
- If the floats do not fit, mount them on the stem from inside the vessel being monitored. Then secure the sensor to the vessel.
- For sensors with float stops, refer to the assembly drawing included with the sensor for float stop installation locations.
- For MPI-E Chemical, ensure probe is concentric with fitting so as not to scrape the chemical-resistant coating off against threads of the fitting.
Electrical Installation Instructions:
- Remove the housing cover of your MPI.
- Feed system wires into MPI through conduit openings. Fittings must be UL/CSA Listed for CSA installation and IP65 Rated or better.
- Connect wires to MPI terminals. Use crimped ferrules on wires, if possible.
- Replace housing cover.
See Sensor and System Wiring Diagrams (section 6) for Modbus wiring examples.
